IPv6: The Challenge

Global growth of the Internet has been driven by the increased use of
computing and communications technology. Mobile equipment, home appliances and
other consumer devices are online and interconnected. Each of these devices
uses an IP address. The current Internet Protocol (IP) addressing system that
Internet devices use - called IPv4 - is predicted to run out of addresses this
year. A new protocol, IPv6, has been introduced to provide a virtually
limitless address space.

The arrival of IPv6 does introduce a new problem for Internet users - IPv4
is not compatible with IPv6. Any services, applications or connectivity over
the public Internet will need to consider integration of IPv6 and IPv6
transition technologies. Basic Internet, web hosting, remote access, mobile
workers, and cloud computing all rely on Internet transport to provide
services.
